Remove "conformsTo", "containedIn", and "currentLocation" of EconomicResource{Create,Update}Params

conformsTo can be set by EconomicEventCreateParams.resourceConformsTo and containedIn is supposed to be set only by assemble and separate (it will set it to null).

Similarly, currentLocation can be set using toLocation with raise and produce events.

While at it, I'd like to ask whether having classifiedAs of EcononomicResourceUpdateParams make sense?
